STIHL Easy2Start™
The STIHL Easy2Start™ system makes starting STIHL outdoor power tools almost effortless, eliminating the need for a strong pull of the starting cord. This advanced starting system is designed to make starting STIHL products fast and easy. The specific system may vary by model, but in each case, a quick pull overcomes the engine’s compression to minimize the strength and effort required to start. Available on selected products.

Multi-Tasking Tool
Switch between any of the eight YARD BOSS® optional attachments quickly.

Multi-Function Control Handle
Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.

Protected Spark Plug Cover
The spark plug cap is integrated in the equipment’s housing, so the spark plug remains protected while still being easy to change.

Purge Pump Primer
A small fuel pump delivers fuel to the carburetor when pushed, reducing the number of starting strokes required following extended breaks in operation.

Rated 5 out of 5 by bear1969 from this is a well built machineI have two chain saws, one pole saw, two weed eaters, one leaf blower and the mini tiller. I am very happy with all of my Stihl products. Bruce at porters in Elwood Kansas takes excellent care of my Stihl products. I highly recommend him.

Rated 5 out of 5 by JJ22 from Very easy to useI got this device to help rework my flower beds. I am amazed how well it preformed. It turns regular dirt into a fine quality potting soil.

Rated 1 out of 5 by Arklonghorn from Not as ExpectedI purchased this product with the wheel attachment hoping to use it around my garden to remove some weeds. It may work great on a single weed, but it doesn't work very good on a patch of weeds. The weeds wrap around the tines and you spend more time pulling weeds from the tines. I used it for 30 minutes and I was not impressed. The last time I went to the garden, I took my wheel hoe and a regular hoe and I was able to get more done with them in less time. I also bought the string trimmer attachment, but I haven't even connected it yet as I may try to take the product back. I have used Stihl chainsaws and string trimmers in the past and I have never been disappointed in a product - until now.
